Occurrence of Cryptosporidium spp. in red foxes and brown bear in the Slovak Republic.

Abstract

Wild animals can be involved in epidemiology of many important diseases and often act as reservoirs of pathogens which cause disease in domestic animals and humans. This paper aims the role of red fox (Vulpes vulpes) and brown bear (Ursus arctos) in the circulation of coccidian parasites from the genus Cryptosporidium. Cryptosporidiosis is known as an important enteric pathogen, clinical symptoms in particular in immune-compromised individuals range from mild to severe diarrhoea and dehydration, which could be fatal. Fecal samples from 62 red foxes shot during September 2010 to February 2011 and 63 brown bears collected during June 2010 to March 2011 in central and eastern Slovakia were examined for the qualitative determination of Cryptosporidium spp. antigens in faeces by sandwich ELISA kit. Overall, 38.7% (24/62) of faecal samples of red foxes and 55.6% (35/63) of faecal samples of brown bear were positive. Our preliminary results emphasize prevalence of Cryptosporidium spp. amongst brown bears and red foxes in Slovakia and highlight the potential risk for transmission of cryptosporidiosis to humans using the countryside for professional or recreational purposes.
